Pardon my intrusiveness, but this sounds like a terrible UI. It's
highly nonstandard and nobody will expect it to behave this way. Why
can't you do things the normal way such that you start off with:
A B C
Z Y X
And when you scroll to the right you get:
B C D
Y X W
This has the dual advantage of allowing you to use NSScrollView and
not confusing your users.
